Mi aplicación de rieles en modo de desarrollo funciona y se ve exactamente como yo quiero, pero en producción se ve diferente en Chrome y Safari, en Safari se cargan las imágenes del logotipo pero no la fuente, en Chrome se carga la fuente pero no la imagen más la entrada los campos son un poco más largos y están mal alineados en Chrome, pero en modo dev todo se ve muy bien en Chrome

Estuve jugando con esto por un tiempo y eliminé el público / activos varias veces
